TRIGger:A:UPP
erthreshold:RF
Arguments
<NR3> is a floating point number that specifies the threshold for the time domain
trace, in degrees.
Examples
SEARCH:SEARCH1:TRIGger:A:UPPerthreshol d:RF_PHASe 15 sets the
upper threshold to 15 degrees.
SEARCH:SEARCH1:TRIGger:A:UPPerthreshol d:RF_PHASe? might return
15, indicating that the upper threshold has been set to 15 degrees.
SEARCH:SPECTral:LIST? (Query Only)
This query will return a list of all automatically placed peak markers displayed in
the frequency domain graticule. (To return information about manual markers,
use the
MARKER:M<x> commands.) This query returns entries in the form of an
enumeration value, which is the source waveform, as well as 7 <NR3> values,
which specify the automatic peak marker attributes.
If manual markers are not turned on, this list will also include the Reference
Marker. (To determine which value is the Reference Marker, query using
RF:REFLevel and compare it with the values.) If manual markers are turned on,
this list will not include the Reference Marker (when manual markers are turned
on, the Reference Marker is MARKER:M1).
Conditions
MDO4000/B/C models only.

Returns
The query is returned in the form:

<Enum> is the source waveform.
The 7 NR3 automatic peak marker attributes returned are as follows:
